تصميم و تصنيع المساند بأطوال مختلفة للمحراث المطرحي القلاب و دراسة تأثيرها في بعض مؤشرات الأداء الحقلي تحت مستويين للمحتوى الرطوبي

الملخص EN

A field experiment conducted In the agronomic season (2012) to study the influence of landside through two levels traditional landside with moldboard plow and the plow with manufactured landside with two levels of moisture content (9.22 – 18.36)%.

according to RCBD which has been used with split plot method and its influence in measuring performance (draw bar force.

slippage percentage.

adhesion force.

vertical and horizontal deviation percentage.

the coefficient of working width exploitation and performance efficiency).

Results of using plow with manufactured landside led to decrease the draw bar force.

slippage percentage.

adhesion force soil and horizontal deviation percentage, it also led to increase the coefficient of working width exploitation and performance efficiency.

While the increase of moisture content led to decrease the draw bar force, slippage percentage, and to increase the performance efficiency.

The interference between the moisture content 18.36% with manufactured landside recorded a decrease in the draw bar force and high value for performance efficiency while the interference between the moisture content 18.36% for the plow with traditional landsiderecorded less slippage percentage and recording less adhesion force with moisture content 9.22% for the plow with manufactured landside.
